Interface InstancingAttributeInfo

Interface for attribute information associated with buffer instantiation

interface InstancingAttributeInfo {
    attributeName: string;
    attributeSize: number;
    attributeType?: number;
    divisor?: number;
    index?: number;
    normalized?: boolean;
    offset: number;
}

Properties

attributeName: string

Name of the GLSL attribute if attribute index is not specified, this is used to retrieve the index from the effect

attributeSize: number

size of the attribute, 1, 2, 3 or 4

attributeType?: number

type of the attribute, gl.BYTE, gl.UNSIGNED_BYTE, gl.SHORT, gl.UNSIGNED_SHORT, gl.FIXED, gl.FLOAT. default is FLOAT

divisor?: number

Modifies the rate at which generic vertex attributes advance when rendering multiple instances default to 1

index?: number

Index/offset of the attribute in the vertex shader if not specified, this will be computes from the name.

normalized?: boolean

normalization of fixed-point data. behavior unclear, use FALSE, default is FALSE

offset: number

Offset of the data in the Vertex Buffer acting as the instancing buffer
